1:5 Clock Distribution

The PI90LV14 implements low voltage differential signaling (LVDS)
to achieve clocking rates as high as 320MHz with low skew.
The PI90LV14 is a low-skew 1:5 Clock Distribution chip which
incorporates multiplexed Clock inputs to allow for distribution of a
lower-speed, single-ended Clock or a high-speed system Clock
When LOWthe SEL pin will select the differential Clock input. By Pericom Semiconductor Corporation
